Cable and producing method therefor

Abstract

A cable is composed of a linear shape conductor, a first electrical insulating member coating a periphery of the conductor, a shield made of a plating layer coating a surface of the first electrical insulating member, a second electrical insulating member coating a surface of the shield, and an exposed shield portion provided in at least one end portion of the cable with the second electrical insulating member being removed therefrom and the shield being exposed therein during termination. An adhesion strength between the shield and the second electrical insulating member in the exposed shield portion is lower than an adhesion strength between the shield and the second electrical insulating member in an other part of the surface of the shield.

What is claimed is: 
     
       1. A cable, comprising:
 a linear shape conductor; 
 a first electrical insulating member coating a periphery of the conductor; 
 a shield comprising a plating layer coating a surface of the first electrical insulating member; 
 a second electrical insulating member coating a surface of the shield; and 
 an exposed shield portion provided in at least one end portion of the cable with the second electrical insulating member being removed therefrom and the shield being exposed therein during termination, 
 wherein an adhesion strength between the shield and the second electrical insulating member in the exposed shield portion is lower than an adhesion strength between the shield and the second electrical insulating member in an other part of the surface of the shield, wherein an arithmetic average roughness Ra of the surface of the shield in the other part thereof is in a range of not lower than 0.5 μm and not higher than 10 μm. 
 
     
     
       2. The cable according to  claim 1 , wherein the surface of the shield faces toward the second electrical insulating member. 
     
     
       3. The cable according to  claim 1 , wherein the second electrical insulating member abuts the surface of the shield. 
     
     
       4. The cable according to  claim 1 , wherein an arithmetic average roughness Ra of the surface of the shield in the exposed shield portion is different from an arithmetic average roughness Ra of the surface of the shield in the other part of the surface of the shield. 
     
     
       5. The cable according to  claim 1 , wherein an arithmetic average roughness Ra of the surface of the shield in the exposed shield portion is lower than an arithmetic average roughness Ra of the surface of the shield in the other part of the surface of the shield. 
     
     
       6. The cable according to  claim 1 , wherein the second electrical insulating member is disposed on the other part of the surface of the shield. 
     
     
       7. The cable according to  claim 1 , wherein the second electrical insulating member is disposed on an entirety of the other part of the surface of the shield. 
     
     
       8. A cable, comprising:
 a linear shape conductor; 
 a first electrical insulating member coating a periphery of the conductor; 
 a shield comprising a plating layer coating a surface of the first electrical insulating member; 
 a second electrical insulating member coating an outer surface of the shield; and an exposed shield portion with the shield being not coated with the second electrical insulating member, 
 wherein an arithmetic average roughness Ra of the outer surface of the shield in the exposed shield portion is lower than an arithmetic average roughness Ra of the outer surface of the shield in an other part thereof, and 
 wherein the arithmetic average roughness Ra of the outer surface of the shield in the exposed shield portion is not lower than 0.1 μm and lower than 0.5 μm, while the arithmetic average roughness Ra of the outer surface of the shield in the other part is not lower than 0.5 μm and not higher than 10 μm. 
 
     
     
       9. The cable according to  claim 8 , wherein the outer surface of the shield faces toward the second electrical insulating member. 
     
     
       10. The cable according to  claim 8 , wherein the second electrical insulating member abuts the outer surface of the shield. 
     
     
       11. The cable according to  claim 8 , wherein an adhesion strength between the shield and the second electrical insulating member in the exposed shield portion is different from an adhesion strength between the shield and the second electrical insulating member in the other part of the outer surface of the shield. 
     
     
       12. The cable according to  claim 8 , wherein the second electrical insulating member is disposed on an entirety of the other part of the outer surface of the shield.
